What are the types of catheters ?
Intermittent urethral catheters, or straight catheters, are used to drain the bladder for short periods.
Indwelling catheter also called retention or foley catheters, is used if it is to remain in place for continuous drainage
Suprapubic catheter is used for long term continuous drainage… Suprapubic catheter is inserted surgically through a small incision above the pubic area. The suprapubic catheters often preferred over indwelling urethral catheters for long-term urinary drainage.
True or false
Suprapubic catheters associated with decreased risk of contamination with organisms from fecal material, elimination of damage the urethra, higher rate of patient satisfaction, and lower risk of catheter associated urinary tract infection
True
What are the three positions you can use when inserting a catheter?
Dorsal recumbent, sims, lateral
How far should you advance an intermittent urethral catheter?
Female: 2-3 inches or (4.8-7.2 cm)
Male: 6-8 inches ( 14.4-19.2 cm)
What are the two major hazards of introducing catheter into the bladder?
Sepsis and trauma
True or false
Although the female urethra shorter than the male urethra, it’s also more susceptible to damage of the catheters forced through it
True
What is bacteriuria?
When a catheter left in place, organisms can move up that catheter lumen for the space between the catheter and the urethral wall. This asymptomatic condition in which bacteria is present in the urine is bacteriuria
What size catheter should you use for long-term use an adult?
14-16 F with a 5-10 ml balloon
What size catheter should you use for older children or infants?
Older children: 8-12 F
Infants: 5-8 F
What is a better position for catheter insertion in females?

What is the most important measure to help prevent urinary tract infections?

True or false
You should apply lubricant to the catheter before inserting it into a male patient
False, the lubricant would remain at the meatus….need syringe with lubricant
When the patient has a urinary tract obstruction a urologic stent may be inserted. What stents are temporary and what are permanent?
Temporary: stent placed in ureters
Permanent: stent placed in urethra

What is an ileal conduit?
An ileal conduit is a cutaneous urinary diversion. An ileal conduit involves surgical resection of the small intestine transportation o ureers to the isolated segment of the small bowel
What is a continent urostomy?
This is a surgical alternative that uses a section of the intestine to create internal reservoir that holds urine
What is the mitrofanoff procedure .
Surgical intervention, where the bladder neck is closed and the appendix is used to gain access to the bladder from the skin surface. One end of the appendix is brought to skin surface and uses a stoma, the other Is tunneled into the bladder
When does a stoma usually stabilize ?
Size stabilizes in 6-8 weeks
How far do stomps protrude ?
1/2 to 1 inch
How long is the female urethra ?
1.5-2.5 inches or 3.6-6 cm
How long is the male urethra?
